mx.symbol.tile

Description

Repeats the whole array multiple times.

If reps has length d, and input array has dimension of n. There are three cases:

  • n=d. Repeat i-th dimension of the input by reps[i] times:

    x = [[1, 2],
    [3, 4]]
    
    tile(x, reps=(2,3)) = [[ 1.,  2.,  1.,  2.,  1.,  2.],
    [ 3.,  4.,  3.,  4.,  3.,  4.],
    [ 1.,  2.,  1.,  2.,  1.,  2.],
    [ 3.,  4.,  3.,  4.,  3.,  4.]]
    
    - **n>d**. ``reps`` is promoted to length *n* by pre-pending 1's to it. Thus for
    

    an input shape (2,3), repos=(2,) is treated as (1,2):

    tile(x, reps=(2,)) = [[ 1.,  2.,  1.,  2.],
    [ 3.,  4.,  3.,  4.]]
    
    - **n<d**. The input is promoted to be d-dimensional by prepending new axes. So a
    

    shape (2,2) array is promoted to (1,2,2) for 3-D replication:

    tile(x, reps=(2,2,3)) = [[[ 1.,  2.,  1.,  2.,  1.,  2.],
    [ 3.,  4.,  3.,  4.,  3.,  4.],
    [ 1.,  2.,  1.,  2.,  1.,  2.],
    [ 3.,  4.,  3.,  4.,  3.,  4.]],
    
    [[ 1.,  2.,  1.,  2.,  1.,  2.],
    [ 3.,  4.,  3.,  4.,  3.,  4.],
    [ 1.,  2.,  1.,  2.,  1.,  2.],
    [ 3.,  4.,  3.,  4.,  3.,  4.]]]

Arguments

Argument

Description

data

NDArray-or-Symbol.

Input data array

reps

Shape(tuple), required.

The number of times for repeating the tensor a. Each dim size of reps must be a positive integer. If reps has length d, the result will have dimension of max(d, a.ndim); If a.ndim < d, a is promoted to be d-dimensional by prepending new axes. If a.ndim > d, reps is promoted to a.ndim by pre-pending 1’s to it.

name

string, optional.

Name of the resulting symbol.
